05 — Graphs and tables

Graphs & tables

NCEA Level 1 · Tables, equations and graphsNCEA Level 2 · Graphical methods (91257)NCEA Level 3 · Conic sections (91573)

Conic curve — templates for circles, ellipses, parabolas and hyperbolas
Polar functions — r = f(θ), up to four
Parametric equation — two pairs of x(t), y(t)

07 — Calculus

Calculus

NCEA Level 2 · Calculus methods (91262)NCEA Level 3 · Differentiation (91578)NCEA Level 3 · Integration (91579)

The MM01 evaluates derivatives at a point and definite integrals numerically. Use it to check the answer you got by hand — that is exactly how it earns marks.

Before you startIf your function contains sin, cos or tan, set the angle unit to Radians (SHIFT Ans). In degrees the derivative and integral will be wrong, and the calculator will not warn you.

Worked example — derivative at a pointGiven f(x) = x³ − 4x², find f′(2).

▶ moves the cursor into the | x = box.

d/dx(X³-4X²)|_x=2

d/dx(X³-4X²)|_x=2

Check by hand: f′(x) = 3x² − 8x, so f′(2) = 12 − 16 = −4.

Worked example — definite integralEvaluate the integral of (3x² + 2x) from x = 0 to x = 2.

∫

The integral template appears, with boxes for the function and both limits.

∫^□_□(□)dX
Type the function: 3 X,T x² + 2 X,T

∫^□_□(3X²+2X)dX

∫²₀(3X²+2X)dX

∫²₀(3X²+2X)dX

12

By hand: [x³ + x²] from 0 to 2 = 8 + 4 = 12.

Numerical, not algebraicIntegration uses a numerical method, so a very long interval or a discontinuity inside the range can introduce error. Split the integral at the awkward point and add the pieces.

Summation Σ

Useful for sequences and series at Level 2 and 3. This one finds Σ(x + 2) from x = 1 to 5.

SHIFTX,TΣ

The stored variables are cleared and you are back at a blank screen.

Reset option	What it clears
Settings & Data	All settings and all stored data
Variable Memory	The variables A–F, X, Y and M
Initialize All	Everything — a full factory reset

Full wipeIf your supervisor asks for the calculator to be returned to factory condition, choose Initialize All at step 5 instead of Variable Memory. Everything else in the sequence is the same.

Then, in the first minute of the exam

Set the Angle Unit — SHIFT Ans — to degrees or radians, depending on the paper.
Confirm Input/Output is on MathI/MathO. A reset returns it there automatically.
Set AutoPower Off to 60 minutes so it does not switch off mid-question: SHIFT MODE → System Settings → AutoPower Off.
Take a spare set of batteries.

11 — Troubleshooting

Error messages

The MM01 tells you what went wrong. Here is what each message means and what to do next.

Message	What has happened	What to do
Math ERROR	A result is outside the calculator’s range, or the calculation is not legal — dividing by zero, for instance.	Check the values you entered and reduce the number of digits.
Syntax ERROR	The calculation is not written in a form the calculator can read.	Press ◀ to go back into the line and fix it — usually a missing bracket.
Stack ERROR	The expression is too deeply nested.	Break the calculation into two or three shorter steps.
Time out	A differentiation or integration did not converge.	Adjust the limits or the tolerance, or split the interval.
Cannot Solve	Solver, differentiation or integration could not find a result.	Enter a starting value closer to the answer you expect, then run it again.
Range ERROR	The table you asked for has more rows than the calculator allows.	Change Start, End or Step to shorten the table.
Variable ERROR	A variable in the expression has no value.	Check the expression and assign the missing value.
Dimension ERROR	Matrices or vectors of different sizes were combined.	Redefine them so the dimensions match.
Not Defined	A matrix or vector was used before it was set up.	Define its size and enter the values first.
Infinite Solution	The system has no single solution.	Check the equations you typed — often two of them are the same line.

Still stuck?Nothing here is unfixable. Get in touch and we will walk you through it — we would rather spend five minutes on the phone than have a student give up on the calculator.
